CUMMINGS, OF SANTA BARBARA, CALIFORNIA, ASSIGIIOR TO WATERTI'IE CASEMENT HARDWARE 00., F 01? CALIFORNIA SANTA BARBARA, CALIFORNIA, A CORPORATION SWINGING EVINDOW AND SCREEN MOU N-TING Application filed August'17, 1928. Serial No. 300,137.

This invention relates to hinged or swinging window mountings of the casement variety and particularly to the special mounting of casement windows in the same frame with hinged or swinging screen frames.

' The objects of the invention are to pro- .vide a mounting of the character described which will facilitate operation of the sash and/or screen, permit "reaching all sides of both screen and sash from within the building, provide a unit fixture easy to apply, avoid the use of casement adjusting rodsin most installations, provide a single locking 1 screen by a single turn of the handle, provide means for movlng thesash to, any posltlon either in or out through'movement of the screen frame, as well as'other features of;

improvement which willappear in the draw- 2G ings and are described in the following specification.

Briefly described the. invention comprises mounting a screen frame and a window sash for outward swinging,'the screen frame {)0 sitioned inwardly of the sash and provided with a latch whereby it may be made to latch the sash atany position of, swinging and causeboth sash and screen to swing together, and maybe unlatchedfrom the sash after the 0 sash has been pushed or pulled open to'the degree desired. Also such mounting of a screen frame and sash in relation to the window frame so as to provide arm space. between sash and window frame, and between screen and sash, so that all sides of sash and screen may be reached for cleaning when the window sash is opened,

In the drawings accompanying this speci- J ficacion Fig. l-is an elevation of my window 7 a building and with sash and screen closed. Fig. 2 is an enlarged cross-sectionof the combination as seen from the line 22 of Fig. 1, but with the-window sash and'scree'n Fig. 3'is an enlarged-verticalsectionof the "lower portion of Fig. lasseenfrom the line '3'-3 thereof.

' 'o'f the central portion of Fig; 1 showing the window frame side lwith several steps to at 5 for the sash and and screen combination as seen from inside of Fig; l is; an enlarged fragmentarysection latch arrangement on the right hand sash and right hand screen frame;

Fig. 5 is an ,enlarged'edge view of one ofthe pivoting fixtures showing the spring washer underth'e lever arm to produce a tight friction joint for holding the sash in any adjusted position of opening.

Inthe drawings 1 is the window sill, 2 the the outwardly swinging screen frame and l a fixed screen frame screwed 0r nailed in place in the window frame. handle which looks .a' sash together with The frame, sill and headpiece are formed provide spaced stops as 6 for the screen frame, so that whenboth sash and screen frames are closed a space will exist between them as best shown in Fig. 3.

Both of the sash frames and one of the screen frames are mounted toswing outwardly on pivoted levers secured to top and bottomof the frames and to the sill and head piece of the window frame as indicated in Fig. 2, the several steps in the sill'and' head piece; and the sash frames being longer than the screen frames; provide for the screen frame and its levers swinging outwardly and 'crossmg over thQilGVQI'S of the sash without interference when both sash and screen are open as shown in Fig. 2.

The mountings for the sash comprise each j pieces, 27 the top or head I 131806, 3, 3 the outwardly swinging sash, 4,

two levers or flat'metal links 7, 8 pivoted at oppositeendsto flat metal plates 91'0 securedr'espectivelyto the sash and the window frame. Plates 9 lie eachina rabbet 11 formed along the upper and lower edge of the sash, and plates 10 lie against a step formed on the head pieceand sill and also bear e'ndwiseagainst a spaced block '12 on headpiece and sill all of which serves for 'quickly positioning the parts correctly when installing.

V The pivotal jointsof the mounting are frictionally retarded by means of a spring split washer interposed between the joint members as indicated at 26 in Fig. 5. e

The lengths, and position of the levers are such as to swing the sash from closed-posi- "tion 'agains't'stope toopen position as indi a fixed cam tiyely frail screen cated by sash 3 in Fig. 2 and when so open the window is stopped from further opening by lever 7 bearing at its edge along the rabbet 11.

The pivotal mounting for screen frame 4: is practically the same as the mounting for the sash above described and consists of levers 13, 14 pivoted to plates 15, 16, tho the spring washers are preferably omitted from the pivotal oints as it is not necessary to frictionally hold the screens in open position as it is the sash frames. Sill plate 16 of the screen mounting is preferably located in a recess in the step of the sill or an extra stool covers it in the manner indicated.

Swinging screen frame fl locks to hook 1-7 projecting from fixed frame l by means of a turnable handle 18 mounted on frame 4t and providedat its outer end with a latch arm 19, the engaged position of the members being indicated in Fig. 1.

Sash 3? is provided with a pair of locking cams 20 which are manually turned to engage a recess plate in sill and head piece asindicat-ed in Fig. 1, where the lower corner of screen frame 4: is broken otfto clearly show the lower cam. Sash 3 is also provided with latch plate 21 adapted to be simultaneously engaged by latch arm 19 when sash 3 is closed as indicated in Fig. 4: so-that when sash 3 is secured with-cam locks 20it willform a rigid member against which screen 4 and sash 3 may be locked by latch arm 19, and thereby avoid making the relaframe a v form the only anc 7 Through the arrangement shown screen frame 4 looks simultaneouslyagainst frame lland sash 3' when the latter is closed.

Sash 3 is manipulated and also locked by means of screen frame 1 by the provision of a latch hook'22 pivotally mounted in the fitting plate :23 on the screen fraine and operated by the thumb piece 24, arranged to engage 'a short bar 25 extending horizontally on and secured to the sash as indicated in F is 2- This bar 25 is long enough to be engaged by the book 22 at any position of the sash and screen regardless of the lateral displacement of'hook 22 relative to sash "on account of the two different arcs traversed by sash a d .en; e e, s e 11 wil $119 6 along the bar while window sash is g'being pnshed c w r-d y for pul ed i ward y- In operation, to opensash 3, the screen frame A: is unlatched and pushed outwardly to force the window sash before it itol desired position. The latch ,hook 22 is then released t am a 2 .01 sa y P u e 9 hu b piece 21: and the screen is closed and locked,

or if si e e l ers s any e released and rushed l t a idlyr yhaad, and scre t am 4: t en losed and i mkeel- S sh 5 alway 9112 1928 closed by reaching it with the hand when screen 4: is opened, and sash 3 may also be cleaned on its inner face when fully or partly open, and on its outer face when closed.

The outer side of sash 3 is reached through the space bet-ween the frame and sash when the latter is open, and the inner, side is easily reached by releasing the screen latch 22 from the sash and swinging the screen parallel with the sash as indicated by the dotted position of the screen frame, and which provides plenty of room between outside of screen and inside of sash for cleaning either.

To close the sash3 when screen 4 is closed the latter is first opened until its hook 22 engages the bar on the sash and whereupon the sash may be pulled" entirely closed .by

means of handle 18 and by a slight turn of the handle both sash and screen are securely locked.

It is, of course, evident without an additional drawing that my sliding hook and bar arrangement 2225 willwork on a sash and screen wherein the sash is hinged with common hinges to the window frame instead of by means of the lever mounting shown, or if both sash and screen are hinged with common hinges but in the latter case-there would not be any arm space forcleaning between screen and window sash, which is one of the objects of the invention.

It is also apparent that in addition to th spring washer retarded joints of the pivot levers any .of the well known casement sash stabilizing adjusters may be used if desired without in any way affecting the invention.
